    INTRODUCTION

    ELMAG-200M is micro-controller based full bore type electromagnetic flow transmitter specially used

    for various industrial applications. This flow transmitters accurately measures the flow rate of conductive

    liquids & slurries in closed pipes. Due to simple, rigid & obstruction less design the flow transmitter is

    a maintenance free instrument in place of conventional mechanical flow measuring device. The use of

    Pulsed DC excitation technology offers highest ability & better measuring accuracy in the form of

    electrical signal 4 - 20 mA DC linearly proportional to volumetric flow.

    ELMAG-200M standard configuration is a sensor with transmitter integrated in one unit. Its performance

    is independent of temperature, pressure, density and viscosity of the medium. The simple design allows

    easy and quick installation of the meter with unskilled personnel.

    ELMAG-200M is a flanged meter available in sizes from DN 10 to DN 300. The rugged flow sensor is

    constructed from completely welded construction. The sensor housing is filled with polyurethane foam

    for excellent protection.

    In the instrument, the sensor and the electronics form one mechanical entity. A retransmission output of

    4-20 mA is provided.

    Sensor: The sensor consists of metering pipe; electrodes and coils. It is accommodated in welded and a

    fully encapsulated steel enclosure, filled with expanded polyurethane, to prevent it from getting exposed

    to moisture and environmental conditions.

    Electronics: The conditioning electronics circuitry is housed in a cast aluminium connection box. The

    termination of this electronics is given in the same housing through cable glands for the required

    connecting cables.

    Applications:

    1) Applications include measurement of flow on conducting liquids, pastes and slurries ( even highly

    corrosive and abrasive) in chemical and petrochemicals, fertilizers, foodstuffs, paper, mining industries etc.

    2) Monitoring water flow in cooling circuits in steel plants, power plants etc.

    3) Measuring flow of clean water, effluent, sludges etc. In pollution and environmental control.

    4) The isolated 4-20 mA output proportional to flow can be fed to PLCs, DCS or remote mounted indicator.

    5) The electromagnetic flow meter is used for measurement of flow of conducting liquids and slurries in a

    wide range on industries such as chemical, petrochemical, fertilizer, pharmaceutical, foodstuff, mining,

    dairy, sugar, breweries, paper, steel etc.

    Operating principle:

    The flow meter is designed for electrically conductive fluids. Measurement is based on Faradays law

    of induction, according to which a voltage is induced in an electrically conductive body, which passes

    through a magnetic field.

    The following expression is applicable to the voltage:

    U = K x B x v x D

    where:

    U = induced voltage

    K = an instrument constant

    B = magnetic field strength

    v = mean velocity

    D = pipe diameter

    FIG.1.

    Thus the induced voltage is proportional to the mean flow velocity, when the field strength is constant.

    Inside the electromagnetic flowmeter, the fluid passes through a magnetic field applied perpendicular to

    the direction of flow. An electric voltage is induced by the movement of the fluid (which must have a

    minimum electrical conductivity). This is proportional to the mean flow velocity and thus to the volume of

    flow. The induced voltage signal is picked up by two electrodes, which are in conductive contact with

    the fluid and transmitted to a signal converter for a standardized output signal.

    This method of measurement offers the following advantages:

    1) No pressure loss through pipe constriction or protruding parts.

    2) Since the magnetic field passes through the entire flow area, the signal represents a mean value over

    the pipe cross-section; therefore, only relatively short straight inlet pipes x DN from the electrode axis

    are required upstream of the primary head.

    3) Only the tube liner and the electrodes are in contact with the fluid.

    4) Already the original signal produced is an electrical voltage, which is an exact linear function of the

    mean flow velocity.

    5) Measurement is independent of the flow profile and other properties of the fluid.

    5.2 How to Install Flow Meter :-

    1) Flowmeter can be installed in any position either vertical or horizontal.

    2) Select a pipe location which will always run full of liquid. Vertical installation with flow

    from down to top assures full pipe condition.

    3) For horizontal installation, the electrode axis should always be in horizontal plane.

    4) Flowmeter is to be installed in such a way that flow is always in the direction pointed by

    red arrow on the instrument.

    5) Suitable gasketing can prevent leakages from near the flanges.

    Flow is not registered at all. 1. Reverse flow direction. 1.Check for correct flow

    measurement direction as

    indicated by arrow on the

    flowmeter.

    Incorrect retransmission output. 1.Retransmission output

    calibration disturbed.

    1.Recalibrate the instrument for

    retransmission output.

    Refer calibration procedure.

    Periodical maintenance :-

    The flow meter does not require any special maintenance. Dependent on the media being measured it

    is recommended that approx. once a year, remove the sensor from the pipe and clean the liner. Method

    of cleaning consists of removing mechanical dirt and any non-conductive coating (like oil film) from the

    liner. A very dirty liner could cause inaccuracy of the measurement. Check mechanical state of the liner.
